High-efficiency DC power systems, hot-swappable rectifiers, and smart communication converters designed for mission-critical infrastructure.
Located in the vibrant international trade city of Guangzhou, China, Guangzhou EVS Powers Co., Ltd. stands as a premier manufacturer of power electronics. We specialize in engineering and manufacturing high-performance switching power supplies, integrated DC power systems, modular power supply units, industrial DC-DC converters, and pure sine wave power inverters.
Through years of technical evolution and a firm commitment to client satisfaction, EVS Powers has established itself as an authoritative OEM/ODM partner. We operate under three pillars: absolute quality assurance, calculated cost optimization, and localized system integration. Serving markets across Europe, North and South America, Australia, the Middle East, and Southeast Asia, our technology powers modern cellular nodes, railway infrastructure, smart grids, and micro data centers.

Addressing power stability, heat dissipation, and footprint constraints in complex physical environments.
Modern base stations require ultra-compact footprint allocations. Our 1U rack-mount rectifiers (like the EVS48100-H1B1) fit into existing 19-inch racks, providing high density switching power up to 3000W at 95% efficiency. Integrated SNMP and Modbus support allow remote NOCs to monitor voltage fluctuations and mitigate cell dropouts.
For roadside traffic monitoring, remote rail signaling, and rural telecommunications, our IP65-rated outdoor cabinets provide environmental protection. They isolate rectifier modules and switching power supplies from rain, moisture, and dust, utilizing integrated heat exchange systems to handle extreme hot and cold climates.
Heavy machinery and power distribution plants rely on robust DC-DC conversion to isolate control circuits from high current spikes. Our 48V to 48V, 12V to 48V, and high current 24V converters maintain galvanic isolation, ensuring microcontrollers, PLCs, and network switches operate without interruption.
A high-performance telecom rectifier is only as good as its weakest component. Under the E-E-A-T guidelines, EVS Powers maintains a state-of-the-art testing facility that performs physical, environmental, and electric stress tests on every batch.
Our laboratory features specialized machinery to replicate real-world deployment challenges: extreme humidity, power surges, line-to-line lightning transients, and thermal dissipation failures. This ensures our power modules function at peak efficiency over a decade-long operating lifespan.
Next-generation hardware innovations designed to meet the demands of global high-capacity communications networks.
We are progressively integrating Gallium Nitride (GaN) and Silicon Carbide (SiC) switches into our rectifiers. By replacing traditional silicon transistors, we can achieve conversion efficiencies exceeding 97%, while shrinking the physical footprint of our 1U 3000W rectifier modules by up to 25%.
Future iterations of our switching power supplies will feature predictive maintenance capabilities. Using real-time monitoring via SNMP v3 and Modbus, these systems will analyze ripple currents, temperature curves, and load fluctuations to flag potential component wear before a failure occurs.
Aligning our products with regional standards to ensure seamless international deployments.
All manufactured units, from 1500W industrial chargers to high-power rectifiers, comply with European CE safety standards and RoHS environmental guidelines to ensure safe operation and disposal.
Our high-frequency switching technology features internal electromagnetic filters to suppress EMI, meeting FCC Class B emission limits and ensuring clean operation alongside sensitive communication devices.
Operating from Guangzhou allows us to coordinate logistics, custom packaging, and export routing to North America, Europe, Australia, and East Asia, reducing delivery times for bulk OEM orders.
